摘要

視知覺（visual perception）功能受限嚴重影響身心障礙者在學習和日常生活的參與，進而對其情緒、行為及社交情形產生負面的影響。臨床和研究人員使用具備良好心理計量特性之視知覺評估工具，有助於精確掌握個案之視知覺功能，並且及早擬定適當之治療計畫。故本研究回顧近十年常使用之視知覺評估工具，及其心理計量特性驗證資料（含信度、效度及反應性），以提供臨床與研究人員選擇視知覺評估工具之參考。研究者合併檢索中英文之電子期刊資料庫中2010年至2019年間常用之視知覺評估工具，再逐一搜尋常用評估工具之心理計量特性。結果顯示常用之視知覺評估工具共三項：視知覺功能測驗（Test of Visual Perceptual Skills, TVPS）、非動作視知覺測驗（Motor-Free Visual Perception Test, MVPT）與視知覺發展測驗（Developmental Test of Visual Perception, DTVP）。TVPS測量的視知覺概念較完整，TVPS和MVPT整個測驗為非動作之施測方式，DTVP則包括動作和非動作的分測驗。TVPS與MVPT之最新版本尚未有心理計量特性的驗證，而TVPS舊版本之心理計量特性檢驗較為充份（如內在一致性、再測信度、收斂效度、建構效度、區辨效度、生態效度）。但三項評估工具都未有反應性之檢驗。建議未來研究可針對各視知覺評估工具最新版本進行檢驗，以提供臨床和研究人員實證依據。

Visual perception deficits greatly affect learning and performance of daily activities in people with disabilities, which results in negative impacts on their emotions, behaviors, and social interactions. Clinicians and researchers should use visual perception assessment tools with good psychometric properties to accurately understand individuals' visual perception and to develop appropriate treatment plans. Therefore, the present study reviewed commonly used visual perception assessment tools in the past ten years and their psychometric properties to provide a reference for clinicians and researchers when selecting assessment tools. We searched for commonly used visual perception assessments between 2010 and 2019 in both English and Chinese electronic journal databases and then searched for psychometric properties of assessment tools. The results showed three commonly used visual perception assessment tools: the Test of Visual Perceptual Skills (TVPS), Motor-Free Visual Perception Test (MVPT) and Developmental Test of Visual Perception (DTVP). The TVPS assesses the concepts of visual perception relatively comprehensively. All subtests of the TVPS and MVPT include non-motor items while the DVPT contains motor and non-motor subtests. Psychometric properties of the latest versions of the TVPS and MVPT have not been examined, whereas the previous versions of the TVPS have been evaluated more thoroughly (e.g., internal consistency, test-retest reliability, convergent validity, construct validity, discriminative validity, and ecological validity). However, these three assessment tools have not been investigated in terms of responsiveness. Future studies should psychometrically test the newest versions of these visual perception assessments to provide empirical evidence for clinicians and researchers.
